关节活动度 ROM

关节活动度（Range of motion, ROM）又称关节活动范围。可以分为被动关节活动度（PROM），助力关节活动度（AAROM）和主动关节活动度（AROM）。

• Passive range of motion (or PROM) - Therapist or equipment moves the joint through the range of motion with no effort from the patient.
• Active assistive range of motion (or AAROM) - Patient uses the muscles surrounding the joint to perform the exercise but requires some help from the therapist or equipment (such as a strap).
• Active range of motion (or AROM) - Patient performs the exercise to move the joint without any assistance to the muscles surrounding the joint.

关节活动度训练（ROM 训练）：恢复或增大关节活动度的一种康复性训练。因关节自身损伤，关节周围组织损伤，神经麻痹以及老年退行性病变等，均可引起关节活动受限。训练可分为矫正性措施和预防性措施。
